  • Publication number: 20140121399
    Abstract: The polymerization of monomers may be at least partially reduced or inhibited by introducing an effective amount of an additive. The additive may be or include a first compound: where: R1 and R2 may be or include an alkyl group, an aryl group, an alkyl group having a heteroatom, an aryl group having a heteroatom, and combinations thereof. The hetero atom may be or include sulfur, nitrogen and/or oxygen. R1 may be the same or different from R2. The polymerizable monomers may be or include, but are not limited to styrene, butadiene, isoprene, acrylic acid, acrylonitrile, vinyl acetate, and combinations thereof.

  • Patent number: 6864286
    Abstract: Novel compounds and pharmaceutical compositions useful as EGFR tyrosine kinase inhibitors. Methods of the invention include administration of the EGFR TK inhibitors to treat diseases characterized by enhanced expression of EGF, including cancers, particularly breast cancer. Additionally, a homology model representing the structure of EGFR kinase domain is provided, which model is useful for the rationally design and screening of compounds predicted to bind favorably to EGFR and to inhibit EGFR TK.

  • Publication number: 20030032832
    Abstract: It has been discovered that the polymerization of unsaturated compounds, such as butadiene, may be inhibited by the addition of a diene and/or alkanolamine inhibitor. The inhibitor is believed to catalytically destroy peroxides present, such as hydrogen peroxide, which may be present in trace amounts. Particularly useful inhibitors include, but are not limited to, ethylenediamine (EDA) and monoethanolamine (MEA).

  • Patent number: 6512023
    Abstract: An adhesive composition includes a polymerizable adhesive monomer, at least one vapor phase stabilizer, and at least one liquid phase stabilizer. The combination of at least one vapor phase stabilizer and at least one liquid phase stabilizer provides superior stabilization and shelf-life for the monomer composition. The stabilized adhesive composition provides superior performance and shelf-life and can be sterilized without significant polymerization of the monomer.

  • Patent number: 6025515
    Abstract: The present invention provides substituted phenols which are effective to inhibit polymer formation during the manufacture of acrylonitrile. Preferred substituted phenols are (a) hindered phenols, nonhindered phenols, and partially hindered phenols, or (b) combinations of hindered phenols with nonhindered or partially hindered phenols. A most preferred substituted phenol is p-nitrosophenol. In a preferred embodiment, the substituted phenols (with the exception of p-nitrosophenol) are combined with hydrogen transfer agents.
